AL Conductor XLPE Insulated 6/10kV 8.7/15kV 12/20kV 18/30kV MV Underground Cable
1. Scope
The cables are manufactured and tested in accordance with IEC60502 Power Cables with Extruded Insulation and their accessories for rated voltages from 1kV(Um1.2 kV) up to 30kV(Um 36kV). Whereas, Greatwall Cable can supply XLPE insulation cables according to other recognized national and international standards or customized specification.
2. Construction and Material
1) Conductor
Conductors are normally class 2 of compacted cicular or circular standard conductors of copper or aluminium.
2) Conductor Screen
All cable of rated voltage above 1.8/3kV are supplied with conductor screening which is non-mentallic and consists of either semi-conducting tape or a layer of extruded semi-conducting compound,or a combination of the two.
3) Insulation
Insulation is a layer of extruded cross-linked polyethylene(XLPE).
4) Insulation Screen
For cable at rated voltage above 1.8/3kV ,insulation screening consists of a non-metallic semi-conducting part in combination with a metallic layer and consists of either semi-conducting tape or a layer of extruded semi-conducting compound.. The extruded insulation screen is normally free strippable(easy removable) type but can be provided with bonded one upon request.
The metallic part is normally applied on the individual cores for rated voltage above 1.8/3kV and on the core assembly for rated voltage 1.8/3kV and consists of plain annealed copper tape. or copper tape screen a layer of copper wire,a lead alloy or corrugated aluminum sheath can be provided upon request.
5) Inner Covering or Separation Sheath
(for armored cables)
A layer of PVC inner coveing is applied under the armor ,if there is no screen.
When the metallic screening and the armor are of different metals, an extruded separation sheath of PVC is provided in order to separate the different metals.
6) Metallic Armor
The armor, if required, consists of single layer of round wires or double tapes of galvanized steel or aluminum or other non-magnetic metals. Single core cables are normally armored with aluminum(other non-magnetic metals), because non-magnetic armor is essential for single core cable for use on A.C circuit .
7) Outer Sheath
All cable are normally provided with an extruded PVC out sheath, black colored(class ST2). Other materials can be available upon request,as PE , polyethylene,high flame or fire retardant PVC and etc.
8) Core Identification
The multiple conductors are identified as according IEC60502 .
